To all whom it may concern:

Be it known that I, Gnouon' A, LnTz, a citizen of the United States, andresident of Plain'field,"in the county of Union and State of New Jersey,have invented certain new and useful linproven'ients in Supports forArticles to be Electroplated, of which the following is a specification.he object of my invention is to simple and efficient means tosupportpipes, conduits, anckanalogous articles within an electroplatingtank or apparatus in such manner that the surface of the articlethroughout its entire length will be subjected to theelectrolyte'andcurrent, and my invention has particular reference tosupporting pipes that are provided with threads at both ends so that theMy invention comprises novel details of improvement and combination ofparts that will be more fully hereinafter set forth and then pointed outin the claims.

Reference isto be had to the accompanying drawings forming part'hereof,wherein,

Figure 1 is a partly broken side elevation illustrating myimprovement-s; Fig. 2 is a view at right angles to Fig. 1; Fig. 3 is anenlarged broke-n detail of the support; Fig. 4 is a section on the line4. 4, in Fig. 3: and 5,111 Fig. 3.

Similar numerals of reference indicate corresi nding parts in theseveral views.

' The numeral 1 indicates a supporting member shown in the form of :1Vrod adapted to be suspended from any suitable support, hanger 2. Rod 1is provided with as shown at 1, to detacha hook or eye on the hanger 2,the hanger 2 being shown cepending from. a rod 3 of a cathode orsupframe of an electroplating apparatus, although rod 1 may be supportedin any suitable manner from such catho frame. Rod 1 is adapted to bepassed through the article to be plated, such as pipe 4, and at thelower end rod 1. is provided with a detachable or adjustable support forthe pipe. For this purpose I have shown support 5 in the form of anangle-plate having a slot or opening 5 receiving the lower end of rod 1.The slot 5 enters support 5 at the angle whereby part of the slot enterseach wall of the angle-planter); I have shown slot 5 as having anenlarged part 5 in one ably engage shown at 2,

threads will be exposed at all parts to the electrolyte.

de or wall and a reduced part 5 in the otherwall communicating at theangle of the plate for the passage laterally through the slot of thelower end. 0t rod 1. Rod 1 is provided with a head 1 at its lower end,beyond. the neck or reduced part 1 of the rod, the part 5 of slot 5being" sufficiently large to receive head 1 while the part 5 of saidslot is smaller than said head, but receives the neck 1 of rod 1,whereby support 5 may be hung upon the rod,

In using my improvements the pipe, tube or article to be plated ispassed over rod 1, the support 5 is moved sideways with respect to thelower end of rod 1 so that the head- 1 and neck 1 pass through thecorresponding parts of slot 5, whereby support; 5 is. hung upon rod 1,and then the pipe is lowered to rest or stand upon support To remove thepipe it ismerely necessaryto move the support 5 sideways to detachitfrom the rod 1. By having the support 5 of metal it forms conductorbetween the pipe and the rod 1. I

In accordance with my improvements the pipes or the like to be platedmay be readily applied. to or removed from the supporting rod, and whensupported upon the rod the exterior surface of the article will be fullyexposed to the electrolyte in the tank of the electroplating apparatusinto which the articles will be lowered. This will be found otadvantage. particularly where pipes or tubes are to be electroplatedthroughout their full length and are provided with screw threads at.their ends which are also to be electroplated, as distinguished frompipe supporting devices known to me which are provided with screwthreaded sockets into which the threads at the ends of the pipes arescrewed tor supporting the pipes, whereby a portion of the threads atleast are thus necessarily let't unplated.

31y improvements will be found advantageous "n apparatuses forelectroplating pipes to serve as conduits for conductors in" electricwiring systems, since it is desirable, where the pipes are electroplatedand provided with thregli'tls at one or both ends, to have such threadselectroplated throughout.

Having now described my invention what I cl aim is:

1. A supporting device of the character described. comprising a rodprovided at its l lower end with ahead, and a support in angular formhaving a slot open through the i angle of the support and extendingpartlv into both walls of the support adapted to rest upon said head. 52, A supporting device of the character described comprising a rodhaving ahead at the lower end and a reduced neck above the head,combined with a plate in angular form having a slot opening through thean- 10 gle' of said plate and extending into both its walls, one part ofthe slot being adapted to receive said head and the other part of the'slot being adapted to receive said neck.

3. Avsupporting device of the character I '15 described comprising a rodhaving a head at the lower end and a reduced neck. above the head,combined with a plate 7 in angular form provided witha slot'extendingg;vthrough the angle into-the Walls of the-platefthe slot being providedwith an enlarged Por- 20 tion inv one wall of the plate to receive-saidhead and with a. reduced portion in its other wallto receive said neck.
